[SCSI] mpt3sas: add new driver supporting 12GB SAS

These driver files are initially, substantially similar to mpt2sas but,
because mpt2sas is going into maintenance mode and mp3sas will become heavily
developed, we elected to keep the code bases separate.

+ * ---------------
+ *
+ * Date      Version   Description
+ * --------  --------  ------------------------------------------------------
+ * 04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
+ * 06-26-07  02.00.01  Added Clear All Persistent Operation to SAS IO Unit
+ *                     Control Request.
+ * 10-02-08  02.00.02  Added Set IOC Parameter Operation to SAS IO Unit Control
+ *                     Request.
+ * 10-28-09  02.00.03  Changed the type of SGL in MPI2_SATA_PASSTHROUGH_REQUEST
+ *                     to MPI2_SGE_IO_UNION since it supports chained SGLs.
+ * 05-12-10  02.00.04  Modified some comments.
+ * 08-11-10  02.00.05  Added NCQ operations to SAS IO Unit Control.
+ * 11-18-11  02.00.06  Incorporating additions for MPI v2.5.
+ * 07-10-12  02.00.07  Added MPI2_SATA_PT_SGE_UNION for use in the SATA
+ *                     Passthrough Request message.
